MANUFACTURING OF MICROPOROUS HEAT TRANSFER SURFACE WITH HIGH HEAT FLUX AND ITS TUBE

摘要

PURPOSE: A manufacturing of micro-porous heat transfer surface with a high heat flux and a micro-porous tube thereof are provided to improve the adhesive force without a post-process of high-temperature plasticity. CONSTITUTION: A base material(21) consecutively transferred by the automatic control jig transferring device(26) is supplied and rotated. Compound powder mixed with pore-forming agent and coating powder is supplied to a hypersonic powder injection device(10). The base material is transferred and rotated with a hypersonic blow nozzle(25). The supplied compound powder is coated on the surface of the base material by accelerating and crashing using compressed gas. A compound powder is coated layer is washed and the pore-forming agent is completely removed.
